Sustanon 300mg/ml – Testosterone Blend
Brand: Dr.X Labs
Volume: 10ml Multi-dose Vial
Administration: Intramuscular (IM) Use Only
What is Sustanon?
Sustanon is a blend of four testosterone esters: propionate, phenylpropionate, isocaproate, and decanoate. This formulation is designed to deliver both rapid and sustained testosterone release, ensuring stable blood levels with less frequent injections.
Key Benefits
- Significant increases in strength and muscle mass
- Enhanced libido and energy levels
- Fast and sustained hormonal elevation
- Suitable for both bulking and cutting cycles
- Improved recovery and training performance
Possible Side Effects
- Estrogen-related effects: gynecomastia, water retention
- Acne and increased aggression in some individuals
- Potential impact on cholesterol and blood pressure
- Suppression of natural testosterone production, requiring post-cycle therapy
Usage Advice & Precautions
Sustanon is commonly used as a base compound in many cycles. It is recommended to include an aromatase inhibitor to manage estrogen, especially with higher doses. Due to the presence of long esters such as decanoate, allow 3–4 weeks after the last injection before starting post-cycle therapy.
